Chemical Name: Triethylaluminum
Simplified Formula: Al(C2H5)3
Appearance: Clear, colorless to pale yellow liquid
Odor: Strong, often unpleasant
Common Use: Catalyst or reagent in polymerization, chemical synthesis, semiconductor manufacture
CAS Number: 97-93-8
Boiling Point: Near 127°C
Solubility: Reacts violently with water
Physical Dangers: Ignites in air, catches fire on contact with water, forms flammable gases
Acute Exposure: Severe skin, eye, and respiratory tract burns or injury
Chronic Exposure: Prolonged exposure damages tissue
Fire and Explosion Risks: Fiercely flammable, explosive mixtures possible
Environmental Impact: Highly reactive, causes secondary hazards
Emergency Overview: Extreme hazard in all forms of handling and exposure
Hazard Pictogram: Flame, exclamation mark, corrosion
Chemical Composition: Pure triethylaluminum, rarely stabilized for lab shipping
Ingredients: Triethylaluminum — no significant stabilizers or contaminants reported
Synonyms: TEA; Aluminum, triethyl-; Ethylaluminum
Concentration: 100% triethylaluminum in most applications
Inhalation: Move to fresh air right away, keep airways clear, seek medical help
Eye Exposure: Flush eyes immediately with water; avoid any rubbing; urgent hospital visit required
Skin Contact: Remove contaminated clothing, drench affected skin with plenty of water, seek medical evaluation
Ingestion: Do not induce vomiting, rinse mouth, immediate medical attention critical
Burn Treatment: Treat as thermal and chemical burns, medical intervention essential
Suitable Extinguishing Media: Class D extinguishers (dry powder), sand — water, CO2, or foam make things worse
Hazardous Combustion Products: Irritant gases, dense smoke, aluminum oxides
Fire Response: Evacuate area, only trained personnel handle firefighting, use proper gear like flame-resistant suits and breathing apparatus
Special Precautions: Explosive vapors, reignition risk, extinguished products stay reactive
Spill Response: Keep people away, ventilate, avoid spark sources, contain with dry materials
Cleanup: Use only trained staff, collect residue with inert dry absorbent, transfer to secure metallic containers
Personal Protection: Full protective gear: chemical suit, face shield, gloves impervious to alkyl aluminum
Environmental Care: Prevent run-off into drains or soil, avoid contact with moisture
Ventilation: Maintain open air, use extraction fans if indoors
Handling Practices: Transfer under inert gas, use closed systems, strict exclusion of water
Storage Requirements: Store in cool, dry spaces; dedicated flame-proof cabinets; away from acids, oxidizers, or water
Container Precautions: Use sealed, compatible metal containers — glass, plastic, or corrodible metals unsafe
Maintenance: Inspect regularly for leaks, proper label retention essential
Personal Protective Equipment: Chemical splash goggles, face shields, flame-resistant clothing, heavy-duty gloves, rubber boots
Respiratory Protection: High efficiency respirators or supplied-air systems where vapor possible
Engineering Controls: Local exhaust, proper ventilation, automatic shut-off valves
Hygiene Measures: Swap out contaminated gear, no food or drinks in workspace, regular decontamination routines
Skin and Eye Protection: Barrier creams or chemical-resistant clothing, safety showers and eyewash stations nearby
State: Liquid at room temperature
Color: Colorless to pale yellow
Odor: Pungent, suffocating
Melting Point: About -52°C
Boiling Point: About 127°C
Vapor Pressure: Moderate at room temperature
Density: About 0.83 g/cm³
Solubility: Reacts violently with water, decomposes
Flammability: Extreme — self-ignites in air and on water
Chemical Stability: Stable under inert, dry atmospheres
Incompatible Materials: Water, alcohol, halogenated solvents, oxidizers, acids
Hazardous Reactions: Contact with moisture triggers fire, explosion, toxic gases
Decomposition: Produces aluminum oxides, flammable gases on breakdown
Polymerization Risks: Significant exothermic reaction risk with improper storage
Acute Effects: Burns all tissue contacted, inhalation causes lung edema and respiratory distress
Chronic Effects: Repeat exposures damage airway and skin, potential for systemic toxicity
Routes of Exposure: Skin, eye, inhalation, accidental ingestion
Symptoms: Severe irritation, redness, blistering, coughing, difficulty breathing, vision damage
Known Carcinogenicity: No established link, but not enough studies to assure safety
Aquatic Impact: Highly toxic to aquatic life, reacts with water forming hazardous products
Persistence and Degradability: Breaks down fast in environment, reaction products still hazardous
Bioaccumulation: No solid data, environmental persistence likely low but impact severe if released
General Environmental Harm: Use only with robust containment, do not allow to enter water bodies
Product Disposal: Handle as hazardous waste, undergoes specialist chemical treatment before landfill or incineration
Contaminated Packaging: Decontaminate with proper agent, recycle or dispose only after neutralization
Regulatory Compliance: Disposal through authorized hazardous waste contractors
Spill Waste: Treat all absorbent and cleanup materials as hazardous
Shipping Classification: Dangerous goods, class 4.2 (substances liable to spontaneous combustion)
UN Number: 1199
Packing Group: I (high danger)
Special Precautions: Transport in sealed, weather-resistant, secure containers under inert atmosphere
Labeling: Flammable liquid, keep away from all ignition sources
National Regulations: Strictly controlled under chemical safety legislation
Workplace Limits: No established occupational exposure limit, considered high hazard
Major Regulatory Bodies: Compliance required with global transport and chemical safety standards
Handling Restrictions: Use by trained, licensed personnel only; documentation required for all movements
